Sharp edges contributes to current or voltage reflection on PCB traces. When a PCB trace turns a
corner at a 90 angle, a reflection can occur. This is primarily due to the change of width of the trace.
At the apex of the turn, the trace width is increased

CHANGES OF COMPONENTS
As discussed earlier in -, the components that we used earlier can be changed to Surface Mount
Devices (SMD) components provided we use double layer PCB. Practically, the incident current will
be returned to the source by the ground

real image is one formed by real light rays and can be

virtual image is one formed by light rays appear to be

CLASSICAL WAVE THEORY
The energy of electromagnetic radiation (such as light)
is in the form of continuous waves and depends on its
intensity. The greater the intensity of the light ( I ), the
greater the power of that light.

Another problem that we managed to analyse is the wide gap between incident and return current
path which will cause coupling between circuits. The voltage regulator and the main board PCB have
quite a wide gap between incident current and return current
